Flatbedders do a little more than hang on to a steering wheel.
And that A/C is damn nice to have after shovelling off half a load of bulk grain (whatever didn't come out the traps, had to be shovelled), or chaining/strapping down a load of steel, and then putting my sides back on and throwing the top tarp back over in 90 degree heat.
We're not all just a bunch of Billy Big Riggers who drive down the road flapping our jaws about our triple digit trucks and bragging about how many miles we can drive in a day.

I'm sure you know the type. These are the ones that have to sit in the truckstops and harrass the waitresses, and are also usually the biggest whiners.
